Abstract: — An electric wheelchair, driven by an electric motor, offers a vital means of mobility for individuals with physical disabilities, particularly those with quadriplegia. Quadriplegia arises from spinal cord injuries, resulting in the loss of function in limbs. However, for some with severe quadriplegia, there remains limited movement, often in the head. Making use of this residual movement, a head-motion controlled wheelchair emerges as a promising solution, affording users the freedom to navigate through tilting motions: forward, backward, right, left, or stable. This innovative robotic wheelchair integrates essential components such as an accelerometer sensor, IR sensor, Raspberry Pi Pico, converter, DC motors, and a motor driver IC. The Raspberry Pi Pico serves as the controller, processing signals from the sensors to initiate wheelchair movement. The wheelchair, designed with cost-effectiveness in mind, prioritizes safety, adaptability, and mobility for its users. By capitalizing on head movements, this wheelchair system empowers individuals with severe quadriplegia, enabling them to independently traverse their surroundings. It represents a significant advancement in assistive technology, tailored to meet the unique needs and challenges of those with mobility impairments.
